**Following are the execution steps:**

1. The issuer server will call the `/service-providers` endpoint.
2. The Carbon Calculator application fetches details for the requested service provider.
3. If the information is found and the account is active, then the application responds with the service provider details and `200` status code.
4. (Optional) If no information is found, then the application responds with the `ACCOUNT_NOT_FOUND` error and `404` status code.
